Software and web development
TkParal is an X Window interface for the Paral program of the former Radio Continuum
Group of the Max-Planck-Institut für Radioastronomie, Bonn.
Paral/TkParal is a convenient tool to plan observing runs at various
telescopes. Based on source position and observatory coordinates it
calculates azimuth, elevation, parallactic angle, rise and set times
and some more parameters.
- APEX "Phase 2" project submission
I developed the web-based "phase 2"
project submission system for APEX projects, starting in 2005 and constantly
improving it until 2017. It has been used by many observers from ESO and Onsala,
and is still used by the Chilean community for the project preparation.
- Fast On-The-Fly Continuum Mapping
Many years ago,
when bolometer arrays had only a few dozens of channels, fast
(or "undersampled") On-The-Fly Mapping was a recommended
method for mapping large areas in a reasonable amount
of observing time. Nowadays, as bolometer arrays with several hundreds
or thousands of channels are in use, this is not so much an issue
anymore. My SMTO working report on "Fast OTF Mapping at the HHT"
is no longer online anyway, unfortunately.
- Fast Switching Phase Calibration
As a post-doc at IRAM Grenoble, I was working on some simulations
about FSPC and its efficiency in mm-wave interferometry. Fast switching phase
calibration is one of the phase correction strategies in use at ALMA. Actually,
the need for FSPC in sub-mm interferometry led to the construction of antennas
which are capable to move with a rate of various degrees/second, and a consequence
of this is that also APEX can move very rapidly between sources. While I still
have my results from back then lying around somewhere, I'm sure that more recent
(and more advanced) work on this topic is available elsewhere.
